  • Niobium Extraction, Refining & Production TIC

    Niobium oxide (Nb 2 O 5) is generally the starting chemical for the production of other compounds, such as niobium chloride (NbCl 5), niobium carbide (NbC), or lithium niobate (LiNbO 3). Niobium metal is produced by the aluminothermic reduction of the oxide followed by electron beam refining.

  • Electron BeamMelting and Refining Niobium

    pyrochlore processing followed by the electron beam melting maybe applied on a muchlarger scale. In this process, the purity of niobium ingots does not depend directly on the purity of Nb205to be reduced because the electron beammelting has an excellent function for niobium purification. Therefore, the electron beam melting and refining
